# ==================== Where To Install Things ====================

# The default location for installation.  Everything is placed in
# subdirectories of this directory.  The default values for many of
# the variables below are expressed in terms of this one, so you may
# not need to change them.  This is set with the --prefix option to
# `../configure'.
prefix=@prefix@

# Like `prefix', but used for architecture-specific files.  This is
# set with the --exec-prefix option to `../configure'.
exec_prefix=@exec_prefix@

# Where to install Emacs and other binaries that people will want to
# run directly (like etags).  This is set with the --bindir option
# to `../configure'.
bindir=@bindir@

# Where to install and expect executable files to be run by Emacs
# rather than directly by users, and other architecture-dependent
# data.  ${archlibdir} is usually below this.  This is set with the
# --libexecdir option to `../configure'.
libexecdir=@libexecdir@

# Directory for local state files for all programs.
localstatedir=@localstatedir@

# Where to find the source code.  This is set by the configure
# script's `--srcdir' option.  However, the value of ${srcdir} in
# this makefile is not identical to what was specified with --srcdir,
# since the variable here has `/lib-src' added at the end.

# We use $(srcdir) explicitly in dependencies so as not to depend on VPATH.
srcdir=@srcdir@
VPATH=@srcdir@

# The top-level source directory, also set by configure.
top_srcdir=@top_srcdir@

# ==================== Emacs-specific directories ====================

# These variables hold the values Emacs will actually use.  They are
# based on the values of the standard Make variables above.

# Where to put executables to be run by Emacs rather than the user.
# This path usually includes the Emacs version and configuration name,
# so that multiple configurations for multiple versions of Emacs may
# be installed at once.  This can be set with the --archlibdir option
# to `../configure'.
